Rep. Greg Walden (R-OR), chair of the National Republican Congressional Committee, said that House Majority Leader Eric Cantor's (R-VA) stance on immigration reform contributed to his primary loss.

“I think Democrats and others who try to read too much into this that isn’t there are making a big mistake that will be fatal to them in the fall,” Walden said on "Fox News Sunday," according to Politico. “I think [immigration] played a role. But again there were a lot of other issues in this race, as well.”

The NRCC chair also said that the race still needed to be analyzed closely.

“You have to go back and do a real analysis of what happened in that race and what didn’t happen in that race,” he said.
